Drilling of a Directional Exploration Well in Turkmenistan in the Waters of the Caspian Sea

Abstract

The purpose of this study was to optimise directional drilling of exploration wells in the Caspian Sea area of Turkmenistan to improve efficiency and reduce environmental impact. The methods employed include the analytical method, classification method, functional method, statistical method, and synthesis method. The study analysed the experience of drilling a directional exploration well in the North Goturdepe field in South-West Turkmenistan with a bottom hole offset of more than 1000 m from the wellhead under anticentral intracavity pressure conditions. The findings of the study confirmed the effectiveness of the new methods to increase hydrocarbon production, reduce time costs, and mitigate the negative impact on the natural environment. This study emphasised not only the significance of modern technological solutions in the energy industry but also their substantial contribution to the sustainable development of the region and energy security.
